1591-1593 9th Ave, San Francisco, CA 94122

The property at 1591-1593 9th Avenue in San Francisco's Inner Sunset neighborhood is a two-unit multi-family residential building constructed in 1939, featuring two stories and classified as a Flats & Duplex building. The most pressing current issues involve active building violations from February 2023, alleging unauthorized modifications including an unpermitted second dwelling unit on the ground level, unapproved wiring, plumbing work, and inadequate fire safety measures. These violations also cite concerns about improper occupancy and safety code non-compliance.

A tenant complaint from February 2023 reported multiple serious concerns, including lack of central heating since October 2022, electrical issues affecting appliance functionality, and a rodent infestation, suggesting maintenance and habitability problems. Additional violations from March 2023 addressed fire safety (missing fire extinguisher) and sanitation issues. The building's improvement history shows some significant renovations, particularly in 2015 when Unit 1 on the second floor underwent bathroom remodels and closet modifications, with corresponding electrical and plumbing work totaling $28,000.

Earlier modifications from 1999 involved substantial basement improvements including multiple bathrooms, laundry areas, a game room, and garage door modifications. The property has experienced recurring issues with unauthorized modifications, as evidenced by an active complaint from 2018 regarding unpermitted remodeling work. A previous illegal short-term rental operation at the property was shut down due to building complaints, and there have been various maintenance issues reported through 311 calls, primarily related to graffiti and street cleaning matters in the surrounding area. The combination of active building violations, maintenance complaints, and unauthorized modifications suggests ongoing regulatory and habitability challenges at this property.
